When attempting to turn on the Study Country Auto Naming application setting in Vault, a server error occurs.
The reason why the error occurs is that the field EDC ID in the Study Country object has a formula within the default value that contains the name__v field. System managed fields cannot be used in formulas which prevents the setting from being turned on.
To rectify this, the name__v field needs to be removed from the formula for the setting to be turned on.
